HKS Silent Hi-power Catback Exhaust 2002-2007 WRX / 2004-2007 STI

Here, you are looking at the HKS Silent Hi-power Catback Exhaust for your 2002-2007 WRX/STI. 

High quality sound. Sport exhaust system with reduced noise level.

Silent Hi-Power mufflers offer high performance and sporty appearance with the added benefit of reduced noise levels making it the best choice for more mature enthusiasts. Silent Hi-Power mufflers are constructed entirely of SUS304 grade stainless steel for high lustre, long lasting performance. For certain applications, HKS has introduced the "Silent Chamber" which removes a lot of the lower frequency noise that can often be heard into the cabin even when cruising. The silent chamber removes this uncomfortable noise but due to its closed end design, only a minimal amount of exhaust gas flows into it, meaning that the disruption to exhaust gas flow through the entire system is minimized and there is no harm to performance.

Details:

• 120mm Polished Tip
• 304 Stainless Construction

Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
